Deleted message recovery in Outlook
When you delete a message in Outlook by pressing the “Delete” button, you can recover the deleted message by searching for it in the Deleted Items folder and moving it to another folder.
A message is permanently deleted when you hold the “Shift” key and press the “Delete” button. Messages are also permanently deleted automatically when the email retention period is met.
Permanently deleted messages can be recovered up to 30 days after deletion.
